When should I use a list comprehension instead of a loop?
Faculty
Use a list comprehension for a short transformation or filter that produces a new list. Use a regular loop when the logic has several steps, needs early exits, or is easier to read one line at a time.

What if I only need to print each value?
Faculty
Use a regular loop. A list comprehension would create a list you do not need.
